We’re looking for a Chief Executive Officer (CEO) to take full ownership of one of AIBY’s core product groups — a 20M-install, $10M ARR consumer subscription business — and scale it into its next phase of profitable growth.

Your mission – maximize the Net Profit and Long-Term Value (LTV) of your multi-platform portfolio of apps across iOS, Android, and web by aligning product innovation with data-driven performance marketing.

Unlike a solo founder, you aren’t starting from zero. As a Business Unit CEO, you have:

• immediate access to AIBY’s historical data from 70+ apps to see what works
• centralized Legal, Finance, and HR so you can focus 100% on the product and the users
• significant UA budgets and infrastructure already in place

What you will do:

• P&L Ownership: you’re 100% accountable for the revenue, marketing spend, and operational costs of your unit
• Strategic Roadmap: define the “Why” and the “When”. You decide which features to build based on their projected impact on retention and monetization
• Growth & Monetization: work hand-in-hand with your UA Lead to optimize ROAS (Return on Ad Spend) and Payback Periods. You’ll oversee the subscription funnel, A/B testing, and paywall optimizations
• Cross-Functional Leadership: build, structure, and scale a high-performing team across Product, Growth, Marketing, Engineering, and Design
• Resource/ Capital Allocation Strategy: you have the autonomy to decide where to “bet” your resources. If a specific app in your unit is scaling, you pivot the team’s focus there immediately
• Partnership with the Board and Founders: you’re involved in strategic decision-making at the C-level, with direct impact on business metrics, financial results, and the product ecosystem

What you should have:

• 7+ years of experience in product-based B2C businesses (subscription, mobile/web)
• 3+ years in leadership roles with direct P&L ownership (CPO, CMO, GM, CEO, Product Director, Head of Product, Head of Marketing, etc.)
• Product-Marketing Hybrid expertise: you can speak “Engineering” to the devs and “ROAS” to the marketers. You understand how a product change affects ad performance and vice versa
• Proven 0→1 and scale-stage experience: launching new units, restructuring businesses, scaling early-stage products to meaningful revenue, or founding a startup
• Strong financial acumen: you live in the dashboards. You understand the nuances of cohorts, LTV/CAC ratios, and churn rates in a subscription-based model
• Mentality: ownership, clarity, decisiveness, speed, and persistence
• Entrepreneurial mindset

What we offer:

• Full strategic and operational ownership of a multi-million ARR business unit
• Competitive fixed compensation + performance-based bonus + long-term incentive structure
• The opportunity to scale a category-leading product portfolio into a global market-defining player
• Results-oriented colleagues committed to scaling impactful products. Your team will help you achieve the most ambitious goals
• Remote-friendly work environment with high autonomy and minimal bureaucracy

THE ROLE

We’re looking for a strong systems-oriented engineer with hands-on LLM experience to join our AI Innovation team. In this role, you’ll build AI systems and internal products that improve how teams work across different departments and areas in the company. The common denominator is ownership: you should be comfortable leading projects end-to-end, including clarifying needs with stakeholders, making decisions under ambiguity, and pushing through blockers when they arise.

This role is a strong fit for someone who enjoys both sides of applied AI work: full-stack engineering and practical use of LLM capabilities.

Hiring manager: Ori Nahum, AI Innovation Team Lead 

What you’ll be working on

Examples of projects you may work on:

• AI agents for code generation workflows (especially in mobile applications)
• A mobile app navigation agent
• Backend services that orchestrate LLM workflows, tool calling, and integrations with internal systems
• AI chatbot connected to internal data sources and business systems
• And other new AI-driven solutions that support different departments across the company

You’ll be expected to move between experimentation and implementation: validating ideas quickly, turning the promising ones into reliable tools, and leading projects far enough to make them useful in practice, not just technically possible.

WHAT ARE WE LOOKING FOR?

Must-have

• 5+ years experience in software development (preferably in Python, TypeScript, or mobile development).
• Ability to lead projects from idea to production, including aligning with stakeholders, driving decisions, and proactively removing blockers when needed
• Hands-on experience building LLM-based products, tools, or agents beyond toy prototypes
• Good understanding of prompt design, tool calling, orchestration, and how to make LLM systems actually useful
• Strong English communication skills

Big advantage

• Experience building internal developer tools or productivity systems
• Background in mobile development, especially native Android or iOS
• Design and implement evaluation frameworks to assess AI performance, accuracy, and reliability.
• Solid understanding of ML theory and how LLMs work under the hood, including key concepts, limitations, and trade-offs beyond the API layer
• Familiarity with cloud infrastructure / DevOps / CI-CD
• Good judgment around where AI adds value and where it doesn’t

Who will do well here

You’ll likely do well in this role if you:

• Like building practical systems, not just demos
• Take initiative without waiting for perfect specs
• Enjoy exploring new tools, but know how to separate hype from what’s actually useful
• Want the freedom to research, experiment, and then ship
• Enjoy working across different problem spaces and use cases, rather than staying in one narrow lane

INTERESTED?

Our recruitment process consists of the following steps: 

• HR interview with the recruitment manager: 45 min
• Technical interview with the AI Engineer Tech Lead & Team Lead: 1 hour
• Take-home challenge: ~ 4 hours of work
• Final Interview - take-home challenge presentation with CTO and AI Engineer Team Lead and Tech Lead: 1 hour

This is a high-impact position where you’ll be involved in the entire product lifecycle: from building core product features and modern UIs to designing a reliable, fast, and efficient infrastructure around it. You’ll work directly day-to-day with the General Manager and have a clear, measurable impact on the product’s unit economics.

Technical stack: AI-driven Engineering, Flutter, Node, TS, React.

We are open to candidates with no prior Flutter experience.

What you need for this position

• You’re an AI-augmented engineer. You actively use tools like Copilot, Cursor, or Claude to speed up your routine, refactor efficiently, and solve problems faster.
• At least 5 years of hands-on experience as a Software Engineer (designing & developing both mobile (primarily) and web applications).
• You communicate openly and feel comfortable in a fast-paced agile team where things can change rapidly.
• You’re a truly product-oriented engineer. You don’t just write code in a vacuum — your technical decisions are always driven by real product and engineering metrics, keeping business goals in mind.
• You can solve product and business problems end-to-end completely solo. You know how to take a high-level problem description and turn it into an efficient, working engineering solution without needing someone to hold your hand.
• Familiarity with Google Cloud Platform, particularly Firebase services including Firestore, Storage, and Performance, as well as experience with Firebase Flutter SDK, Bloc, and Hive storage.
• Hands-on experience building backend (Node.js and Lambda preferred). We value any strong backend background; if you haven’t used our specific stack, we expect you to bridge the gap using AI tools and a high “speed of learning” to ship production-ready code.

What You’ll Be Doing

• Design, build, and maintain mobile app and its infra using Flutter and a Node.js backend. Develop and optimize web-frontend (marketing funnels).
• Leverage AI tools (Cursor, Copilot, etc.) to accelerate development, refactor code, and maintain high code quality.
• Take an active role in product management: monitoring how users interact with your features and identifying areas for improvement. You will analyze user flow through marketing funnels, identifying drop-off points and technical bottlenecks that affect conversion. You won’t just wait for tasks; you’ll proactively suggest tech improvements based on data insights.
• Design and implement A/B tests to validate hypotheses, working closely with the product team to optimize core metrics.
• Build a robust, scalable infrastructure.
• Work directly with the General Manager and marketing team to align engineering efforts with business growth and scalability.

Hiring Process

Stage 1: Interview with HR (1h).

Stage 2: Interview with VP of Engineering.

Stage 3: Technical interview.

Stage 4: Interview with the team.

What we offer for your success

• Very warm and friendly working environment and flexible working schedule.
• 20 days off + paid national holidays, and 12 sick days paid by the company per year.
• Medical insurance, and health protection programs (with COVID-19 and dental coverage).
• Continuous professional development and growth opportunities.

At Brainway, we operate as a premier R&D-as-a-service and software startup partner, helping companies scale their technical capabilities with top-tier engineering talent. We are currently searching for a Senior Go Developer to join an innovative, US/Israel-based fintech company as a dedicated outsource developer.

In this role, you will be deeply integrated into the fintech partner's engineering team, taking ownership of complex backend challenges. You will bypass typical bureaucratic layers and report directly to the Technical Manager on the client side, ensuring agile decision-making and clear technical alignment. If you are a self-driven engineer who thrives in taking extreme ownership of scalable backend architectures in a fully remote environment, this is the role for you.

What You Will Do

• Design, develop, and maintain high-performance, scalable, and reliable backend services using Go.
• Work closely with the client's technical leadership and distributed team to align system architecture with business objectives.
• Take full ownership of the software development lifecycle for your services, from technical design and coding to deployment and monitoring.
• Identify and resolve performance bottlenecks, ensuring systems are highly optimized for scale.
• Promote engineering best practices, conduct rigorous code reviews, and help shape the technical culture of the remote team.

What We Are Looking For

• Core Go Expertise: 5+ years of software engineering experience, with a heavy, recent focus on building production-grade backend systems in Go. Deep understanding of Go's concurrency model (goroutines, channels), memory management, and standard library.
• Microservices & API Design: Proven experience designing and implementing microservices. Strong hands-on experience with gRPC and Protocol Buffers (Protobuf), as well as RESTful API development using modern Go routers/frameworks (e.g., Gin, Chi, or Echo).
• Data & Event-Driven Systems: Deep experience with NoSQL databases, specifically MongoDB (using the official mongo-go-driver and handling BSON data), and caching/in-memory data stores like Redis. Proven track record working with message brokers and event streaming platforms like Apache Kafka or RabbitMQ.
• AI-Assisted Development: Practical knowledge and experience integrating AI coding tools (such as Claude Code, GitHub Copilot, or similar agentic solutions) into your daily workflow. You must be able to clearly present and explain the methodologies, workflows, and specific techniques you use to accelerate development and improve code quality.
• Infrastructure & Cloud: Solid familiarity with containerization (Docker), orchestration (Kubernetes), cloud infrastructure (preferably AWS or GCP), and advanced CI/CD pipelines.
• System Design: Deep experience writing maintainable, testable code, combined with a practical understanding of domain-driven design and building highly available, fault-tolerant distributed systems.
• Remote Autonomy & Communication: Excellent English communication skills with the ability to work independently in a remote outsourced model while maintaining tight synchronization with the US/Israel leadership team.
